Birger Koblitz 63a0a4d85b realtek: Add support for RTL9300/RTL9310 I2C controller
This adds support for the RTL9300 and RTL9310 I2C controller.
The controller implements the SMBus protocol for SMBus transfers
over an I2C bus. The driver supports selecting one of the 2 possible
SCL pins and any of the 8 possible SDA pins. Bus speeds of
100kHz (standard speed) and 400kHz (high speed I2C) are supported.
